Analysis on Ecological Security of Land Resources in Changsha-Zhuzhou-Xiangtan Urban Agglomerations Based on Ecological Footprint

Ecological footprint was an analysis method for measuring land resource ecological security.This paper analyzed the ecological footmark and ecological capacity of Changsha-Zhuzhou-Xiangtan urban agglomerations in 2007 by ecological footprint model to fatherly discuss the status of land resource ecological security.The results showed that the needs of ecological footprint per capita was 2.5800hm2,the supply was only 0.4415hm2,the ecological footprint deficit was 2.1915hm2.The results indicated that although it was strive to enhance the land use efficiency in Changsha-Zhuzhou-Xiangtan urban agglomerations,its development model was not sustainable,and the land resource system was almost in the ecology over burden condition,the status of regional land resource eco-security was belong to the insecurity grade.At last,in order to provide some reference in the experimental work about building resource-economical and environment-friendly society of Changsha-Zhuzhou-Xiangtan urban agglomerations,this paper gave some useful suggestions to prove the security status of regional land resource system.
